Q=Data withheld because the Relative Standard Error (RSE) was greater than
50 percent, or fewer than 20 buildings were sampled.
N=No responding cases in sample.

Notes:
● Statistics for the "Energy End Uses" category represent
total consumption in buildings that have the end use, not consumption
specifically for that particular end use. ● HVAC = Heating,
Ventilation, and Air Conditioning. ● Due to rounding, data may not sum
to totals.
